AUTOMATICALLY-OPERATED RAILROAD GATE.

Specification of Letters Patent. Pnji g tgfl Jugg e 2Q, 1922,

Application filed December 30, 1921. Serial No. 526,008.

T 0 aZZw/wm it may concern:

Be it known that 1, dessert Niiirnrr, citizen of Hungary, residing at Trenton, in the county of Mercer and State of New Jersey,

have invented certain new and useful Inn provements in Automatically()perated Railroad Gates, of which the following is a specification.

This invention relates to an automatically operated railroad gate and it has for an obj ect toprovide a simple mechanism whereby a railroad gate is automatically closed when a train approaches, and opened when the train has passed, a further feature relating to the provision of a signal for giving notice of the approach of the train.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the follow ing description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a plan view show ing my improved automatic gate applied to a railroad track.

Fig. 2 is a longitudinal vertical section on the line 2-2 of Fig. 1.

In the drawings 1 have shown a section,

of a railroad track comprising the rails 10 and ties 11, a portion of an intersecting road being indicated at 12. The gate comprises a post 14 on which is hinged, a short distance from one end as at 15, a gate bar 16. Located at a suitable distance along the track on opposite sides of the road 12 are trans verse shafts 18, 18 supported at opposite ends by fixed bearing brackets such as 19., these shafts extending under the rails 10. While I have shown, and will describe, only one gate it is to be understood that there is a gate provided on each side of the track and that each end of the shaft has like gate op erating elements connected thereto.

Mounted rigidly on stubshafts 20. 20, which are above and parallel to the ends of shafts 18, 18, are drums 21 and 21 from which wires or cables 22 and 22' lead, around suitable pulleys 23, to the gate bar 15, causing the latter to swing when the shafts 18, 18 are rocked. Fixed on the shafts 18,18 are gear pinions 2st and 24. which engage gear segments 25, 25 fixed on arms 26, 26 hinged to brackets 27, these gear elements being located midway between the rails 10. Fixed to the ends of shafts 18, 18 are gear pinions 30, 80 which engage gears 31, 31 fixed on the stub shafts 20, 20". The segment arms have slot and pin connections 35 with forked bracing .arms 36 hinged to brackets 37.

The shaft 18 and its associated parts are located on the side of the road 12 from which the train approaches, the shaft 18 and its associated parts being on the other side. When the gate is open the segment arm 26 is inclined forwardly and upwardly from its pivot end as shown, while the segment arm 26 lies horizontal. When a train approaches the gate a suitable part on the understructure thereof engages the arm 26 and depresses it, causing shaft 18 to be rotated by the engagement of segment 25 with pinion 2a and the drum 21 to be rocked by the engagement of pinion 30 with gear 31, pulling on cable 22 and swinging bar 15 to a horizontal position. At the same time cable 22 is also pulled, and drum 21 is rocked, causing shaft 18 to be rotated and segment arm 26 raised to an inclined position. TVhen the train has passed the road 12 the arm 26 is engaged and depressed, rocking drum 21, and pulling on cable 22 which raised bar 15 to its original position. At the same time cable 22 is pulled by the gate bar 15, rocking drum 21 and restoring segment arm 26 to its inclined position.

The signal means which I have provided comprises a bell 35 set on a post 36 which supports one of the pulleys 23. Pivoted on the post 36 is a clapper 38 which is urged away from the bell by an expansion spring 39. To the clapper 38 is attached a cable 10 which leads around pulleys s1 and along the track to point in advance of the seg ment arm 26, connecting to a vertical offset 12 from an inclined flat spring 13 fixed adjacent one rail and adapted to be depressed by the wheels of the trainreturning to its normal position by its own resiliency. As will be apparent the successive engagement of the wheels of the train with the spring 43 will cause the clapper 38 to be vibrated and the bell to sound.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. An automatically operated railroad gate comprising a movable gate member, a normally upwardly inclined arm, a normally horizontal arm, and operative connections between said arm and the gate whereby depression of one arm closes the gate and raises the other arm, and depression of the second arm opens the gate and raises the first. arm, said connections including gear segments fixed on said arms, a pair of drums, gear consite directions therefrom, drums on which said ropes wind, a pair of hinged arms, and 15 operative connections between said arms and drums whereby the arms are operated inversely in unison, said connections including gear segments fixed on said arms, a pair of shafts extending transversely of the track, 20

gear pinions on said shafts meshing with said gear segments, and gear and pinion con nections between said shafts and drums.

In testimony whereof I have afiixed my signature.

JOSEPH NEMETY.
